First, the header near the top of the page should probably be "Static Methods and Properties," not "Shared Methods and Properties."
Next, this sentence:
quote:
The introduction of the Shared keyword means that a class is no longer required,
...should be:
quote:
The introduction of the static keyword means that a class is no longer required,
And the last code block:
Utils.Log("An exception occurred");
...should be:
Tools.Log("An exception occurred");

You are correct on all counts. The shared/static thing was, from looking at my chapter, something that got backed out and I'm not sure why.

Hi Dave,
I see you are the author of chapter 9. I don't mean to pick on you; the errors in chapter 9 are, I think, representative of the problems found throughout the book. There was a Try It Out in chapter 7 with a Details View control that I simply couldn't get to work -- I went through it a couple of times, and every time I got a runtime error when I tried to update the record.
The point I was trying to make was: I think it would be good if someone at Wrox went through the book to make sure the examples are correct. For example, on page 634 the solution for exercise C in Chapter 9 (NOT A > 0 OR A < 5) reads:
quote:
True for integers 5 and below. Integers 6 and above will evaluate to False.
5 < 5 == True...?
